OA. The distribution is right-skewed because the peak is between 0 and 5 minutes and the right tail is much longer than the left tail.
OB. The distribution is bell-shaped and roughly symmetric about its peak between 25 and 30 minutes.
OC. The distribution is left-skewed because the peak is between 55 and 60 minutes and the left tail is much longer than the right tail.
OD. The distribution is right-skewed because the peak is between 5 and 10 minutes and the right tail is much longer than the left tail.
(b) Construct a boxplot of the data. Are there any outliers?
